Company description

We are a clinical-stage specialty pharmaceutical company developing and commercializing therapies for the treatment of retinal diseases. We are developing KIO-301, with an initial focus on patients with later stages of vision loss due to retinitis pigmentosa (collectively including any and all sub-forms, "RP"). KIO-301 is a potential vision-restoring small molecule that acts as a “photoswitch” specifically created to restore vision in patients with inherited and age-related degenerative retinal diseases, including RP. We completed a Phase 1b clinical trial in September 2023 and presented topline results in November 2023 at the American Academy of Ophthalmology Annual Meeting. The full data package triggered multiple discussions with various potential pharmaceutical partners. After assessing available options, in January 2024, we partnered with Théa Open Innovation ("TOI"), a sister company of Laboratories Théa. In October 2024, we received regulatory approval to initiate a Phase 2 clinical trial to investigate KIO-301 in patients with retinitis pigmentosa. The ABACUS-2 trial is a 36 patient, multicenter, double-masked, randomized, controlled, multiple dose study enrolling patients with ultra-low vision or no light perception regardless of their underlying gene mutation associated with retinitis pigmentosa. Enrollment in the ABACUS-2 trial is currently ongoing. As KIO-301 and its sister molecules are ion channel modulators, the potential to treat other neurological diseases exists. KIO-301 (formerly known as B-203) was acquired through the Bayon Therapeutics, Inc.
